我们现在有个23D的项目，在adc校准的时候出现METAAPP_TIMEOUT的字样，看了下log

2010-1-5 11:17:36. 15 FAIL: ADC measure (ADC cal timer)
正常的测试为

用MET看了下可以正常的算出相应的SLOPE ,不知道哪里出了问题。
（校准工具已经验证没有问题，测试线也check过）

把ADC通道改一下就OK了
已经改了配置文件里面的，v 6,c 5,没有用
改校准文件，校准文件里面只要ADC control,把ADC table删掉！
是不是用的四相电源?
没有用哦，电源用的66311B
是不是有的行，有的不行OR都不行
電源是663XX時,看看電源電壓會不會跳動, 如果跳動較大, 要改一個cap type
已经解决了，是打印串口信息没有关掉
打印串口信息怎么关闭啊?我也碰到同样的问题
